/**
 * 使用RabbitMQ
 *  1.引入amqp场景 : RabbitAutoConfiguration就会生效
 *  2. 给容器中自动配置了
 *      RabbitTemplate、AmqpAdmin 、CachingConnectionFactory 、RabbitMessagingTemplate
 *
 *  3.给配置文件中配置 spring.rabbitmq 信息
 *
 *      @ConfigurationProperties( prefix = "spring.rabbitmq")
 *      public class RabbitProperties
 *
 *  4.@EnableRabbit: @EnableXxxx 开启功能
 *
 *  5.监听消息:使用 @RabbitListener ：必须有@EnableRabbit
 *      @RabbitListener：类+方法都能标注 （监听哪些队列）
 *      @RabbitHandler: 可以标在方法上 (重载区分不同的消息)
